VENTILATING APPARATUS Filed Oct. 1, 1928 ATTORNEY,

Patented June 24, 1930 urrso STATES masses PATENT OFFICE EDWARD P. GRISHAM, OF ST. L0UI S, MISSOURI' VENTILATING APPARATUS Application filed October 1, 1928.

This invention relates to ventilating appavide a ventilatin apparatus which will embody such an arrangement of its component parts that it may be caused to have a highly attractive appearance thus providing for ventilation of the room in which it is installed without the use of unsightly ventilator gratings installed in the walls of a room or other ventilating means presenting an unsightly appearance.

Another object of the invention is to provide an arrangement whereby the ventilating means may be combined with illuminating means so that the structure, as a whole, will present the appearance of a floor or table lamp as well as serving as such in addition to operating as a ventilating means.

While the accompanying drawings and the description which is to follow, constitute a disclosure of the preferred embodiment of the invention, it will be understood that various changes may be made within the scope of what is claimed.

In the accompanying drawin s:

Figure 1 is a view in elevation of one form of ventilating apparatus embodying the invention, the same being illustrated as in stalled in a room and the room being shown in section; V p

Figure 2 is a horizontal sectional View taken substantially on the line 22 of Figure 1 looking in the direction indicated by the arrows.

The apparatus shown in the drawings is designed to operate in a manner to draw fresh air from the exterior ofthe building into the room to be ventilated and to deliver the airin a manner to effect the desiredventilation of the room and as illustrated in these figures the apparatus includes a hollow substantially cylindrical base 1 which may be of sheet metal or any other material found suitable for the purpose and which may be ornamented in any desired manner, the base being ar- Serial No. 309,493.

ranged upon the floor of the room 2 in which the apparatus isinstalled. it tubular standard 3 is mounted at its lower end in the top of the base 1 and extends vertically from the central portion of the said base and nearly to the ceiling of the room, any suitable ornamental braces 5 being provided for bracing the standard withrespect to the base as shown in Figure 1 of the drawings. In the illustrated embodiment, a cluster of electric light bulbs 6 are installed in sockets 7 supported at the outer ends of tubular arms 8 which radiate from the'standard 3 at a suitably elevated point corresponding substantially to the height of the ordinary electric floor lamp and the standard 3 is extended above the bracket members or arms 8 and a shade 9 is preferably mounted upon the standard and surroundsthe cluster of bulbs 6, an inverted substantially conical spreader 10 being mounted upon the upper end of the'standard with its major open end presented toward the ceiling 4 but spaced fromthe same as shown in Figure 1." j r As shown in the drawings a rotary air 'compressor 11 is mounted within the base land the lower end of the tubular standard 3 is fitted into the outletofthe compressor casing, an electric motor 12 being likewise ar-' ranged within the base 1 and a conduit 13 beso ing arranged beneath the floor of the room and having a branchrextending upwardly and a short distance into the base 1 to permit of the conductor wire 14 which supplies the current, being connected with the motor 12, a branch 15 being led from this wire upwardly through the standard 3 to the sockets for the electric light bulbs 6. s r The numeral 16 indicates an air conducting pipe one end of which is led into the base .1 and connected withthe intake of the compressor casing 11, the other end of the pipe being placed in communication with the atmosphere exteriorly of the room in which the apparatus is installed by being led to one of the windows of the room as vention it will be understood that when the motor 12 is energized and the compressor 11 is driven thereby, a strong current of air will be induced through the conducting pipe 16 as indicated by the arrows in Figure 1 and delivered through the tubular standard 3 in a stream directed upwardly against the ceiling 4 and through the open major or upper end of the spreader 10, the blast of air being broken up and caused to spread in all directions, upon striking the ceiling surface, as indicated by the arrows in the said Figure 1. In this manner fresh air is supplied to the room and caused to circulate therein thus keeping the room well ventilated and suitably cooled. It will beunderstood that any suitable switch (not shown) may be employed for controlling the supply of current to the motor 12 independently of the supply to the light bulbs 6 and it will also be understood that the standard 3 will be of suflicient internal diameter to permit of the conductor wires 15 being led therethrough without materially interfering with the flow of air under pressure through the standard. Having thus described the inventlon, what I clalm 1s:

Ventilating apparatus comprising a hollow base, a rotary air compressor housed within the base, motor means for driving said compressor also housed within the base, the compressor including a casing having an inlet and an outlet, a tubular air conducting standard having its lower end extending into the base and in communication with the outlet of the compressor casing, an inverted conical distributor mounted upon the upper end of the said standard whereby to be presented toward the ceiling of a room in which the apparatus is installed, and a fresh air intake pipe in communication with the inlet of the compressor. 7

In testimony whereof I affix my signature.

EDWARD P. GRISHAM.
